It is produced and provided by a client, but all the sound sources released in Korea are this production version. I think the sound source is better than the one without it, so I’m sending it to you. Think of it as a bonus, and I recommend you to listen to it and decide whether to use it. We will send you an MP3 e-mail for reference. Recently, National Geographic Kids was published as a licensed version in China. The Chinese publisher officially produced the sound source, but the license version is small. We will give you a total of 54 sound source streaming addresses from pre to stage 2. Reference sound source MP3 + official sound source streaming address e-mail sending
